British actress Billie Piper has reportedly signed up to take her DOCTOR WHO TV role to Hollywood in a big-screen version of the sci-fi show. Piper played the Time Lord's sexy sidekick ROSE TYLER in the television show before quitting the series this year (06). And TV bosses, who came up with the idea of a feature film after selling the show to the US, are determined to woo back the beauty for a reunion with the doctor. An insider tells British newspaper the Daily Star, "There's been so much interest in Doctor Who since the show was sold to America that a film is the natural progression. "Top of our list is to get Billie on board. Not only was she amazingly popular, it would be really exciting to get her back with the Doc."
